The Sex and the City storyline so inappropriate, Kim Cattrall wouldn't go through with it.

From golden showers and grey pubic hairs to tantric sex and orgies, the series about four single women navigating dating life in New York covered everything you wish you could talk about with your friends.

Undoubtedly, the most sexually adventurous character was the incomparable Samantha Jones, who was unashamedly open (and detailed) about her appetite for sex.

But speaking on the podcast Origins, with James Andrew Miller, Sex and the City show creator Michael Patrick King said there was one storyline actress Kim Cattrall, who played Samantha, wouldn’t go through with.

“There was one storyline where Kim said, ‘This is too far,’” said King on the podcast.

“It was [Samantha] talking to a 13-year-old girl about a blowjob, and we changed it.”

Yes, most of Sex and the City’s storylines pushed the boundaries of what was acceptable for women to talk about, let alone do, at the time. But we can understand why Cattrall would draw the line at involving a child in conversations about sex.

The podcast series which is deep diving into the beginnings of the iconic HBO show on its 20th anniversary also features interviews with cast members Kristin Davis, Cynthia Nixon, Sarah Jessica Parker and Chris Noth.

When asked who was most like their characters in real life, Davis, who played Charlotte on the show, could only really definitively say who wasn’t like their character.

“Definitely not Kim. Kim is not like Samantha, she was never wild like that, not as brash. She said this herself, she was kind of a homebody, very well-read, you know, had a different energy,” Davis said.

“But I think she said, and I hope I’m right, that she learnt a lot of Samantha. From her strength and joy of life.”

As did millions of women around the world.
